How to measure the performance of asp.net on different servers?

Question

IIS

There is a garden of 500 servers with a variety of hardware and software.
Websites on IIS + MS SQL are deployed in the garden. There is a problem of system performance on large projects - I really want to "feel" the current installations without iron synthetics, but on a real example of the program running on IIS, and at the same time measure the performance and reliability of the web farm.
Please share your experience/knowledge/good links.

Answer 1

Well it is possible the simple decision in a forehead through global.asax on begin_response and end_response simply to measure processing time. Measure the processing time on different servers in this way. It is convenient to see the performance of the application itself with dotTrace. off.site says that he can work with remote servers.
